The invention relates to radiators and more particularly to those of the-so-called baseboard type wherein the radiator is disposed close to the floor and adjacent the base board of the room or other place to be heated.

The object of the invention isto provide a radiator in which the interchange of heat will not only be eificiently effected by convection but at the same time the heat receiving chamber is so constructed and arranged as to provide for heating the room or other place to be heated by radiant heat.

A further object of the invention is to pro- 5 vide a radiator made up of one or more radiator units and in which the valve and pipe connections leading to and from the radiator are concealed in compartments at the ends of the radiator.

The invention further consists in the several features hereinafter set forth and more particularly described by claims at the conclusion hereof.

Fig. 2 is a detail horizontal sectional view taken on the line 2-2 of Fig. 1;

Fig. 3 isa detail vertical sectional view taken on the line 3-3 of Fig. 2;

Fig. 4 is a detail vertical sectional view taken on the line 4-4 of Fig. 3;

Fig. 5 is a detail vertical sectional view r taken along the line 5-5 as shown in Figs. 0

1 and 2.

As shown in the drawings, the radiator itself is made up of one or more units 6. Each of these units is formed to provide a heating fluid receiving chamber 7 whose front face 8 is designed to give the maximum area for the transmission of radiant heat. This chamber 7' has a main front portion or space 9 preferably tapering upwardly from the bottom thereof as shown in Fig. 3 and a series of rearwardly disposed, spaced channels 10 freely communicating with the space 9 and extending generally vertically through walls 11 forming these channels and preferably of tortuous or zig-zag or corrugation formation as shown in Fig. 4.

The chamber thus formed is spaced from the bottom, rear and top of the unit by series of spaced fins 12 which extend vertically from the top and bottom of the heating chamber as well as from the rear butwhich at the rear connect with the walls of the unit forming the channels 10 so that a series of s aced channels 13 and 14 are formed by sai fins,

the channels 14 being of less depth in the rear than the channels 13 which because of the corrugated or zig-zag formation of the walls 11 are also of similar formation at the rear where these walls 11 form part of such channels. The fins 12 are connected together at their top and bottom edges by the parts 15 and 16 respectively and they may also have a rear cover plate 17 associated therewith as shown in Fig. 3 and secured by screws 18 or other suitable fastening means to the edges of some of the fins, said fins preferably having the inclined portions 19 and 20 with the cover plate arranged over the-same so that the air will be efiiciently introduced into the channels 13 and 14 and efliciently discharged from the same.

From the foregoing it will be noted that the fin and channel construction of the unit is such that the air that passes through these channels will be efficiently heated by convection heat and discharged into the room from the upper end of the channels.

The heating chamber is adapted to receive any suitable heating medium such as steam, vapor vacuum or hot water and for this purpose each unit is provided with spaced threaded openings 21 andv 22 adapted to receive pipes, pipe plugs or pipe couplings as the case may be in connection with the assembly and installation of the unit or interchangeable units. Where a plurality of units are assembled together as shown in Fig. 1, the couplings for securing these units together are shown in detail in Figs. 2 and 4 wherein the alined openings 21 of adjacent units are secured together by pipe couplings 22 having right and left nipple portions and a'flange portion 23 adapted for turning the same and associated with sealing gaskets 24. These may also be secured together at their top and bottom 1o valve 27 associated therewith or any other portions by screws or other suitable fasten- 1mg means. It will also be observed that the front portionsof adjacent units at the heating chamber, to and bottom walls respective- 5 1y, are arrange in abutting relation.

. At the inlet end, the upper one of the o n ings 21 is closed off in known manner as y a suitable ipe plug while the inlet pipe 26 is connected with the lower opening 21 in known manner and has the control valve such as the suitable control mechanism. At the outlet end, the iilipper one of the openings 21 is plugged 0 while the outlet pipe 28 is connected with the lower of these openings and may have an air vent valve 29 associated therewith where steam is used.

In order to improve the appearance of the radiator, I have provided a compartment 30 for concealing the inlet pipe and valve and preferably another similar compartment 31 for concealing the discharge pipe connections. As these compartments are similar, the one for concealing the valve has been shown in detail.

Referring to the Figs. 1, 2 and 5 each compartment is formed to provide side walls 32 and 33, bottom wall 34, top wall 35, a front lower grilled wall 36, a front plate 37 secured by screws 38 to the upper end of wall .36 and a grilled front cover plate 39 hinged at its lower end by a hinge pin 40 to the upper end of the plate 37 and resting at its upper end against the outer edge of the top wall 35, and a back plate 41 is also preferably secured in any suitable manner to the side walls. The side wall 32 is apertured at 42 to accommodate the inlet pipe connection and the bottom wall 34 is apertured at 43 for a similar purpose. The unit. thus formed is secured to the adjacent radiator unit by screws 44 passing through the side wall 32 and with the ad acent wall portion of the radiator unit. With this arrangement where the hinged is given ready access to the valve. 27. It will also be observed that the grill work of these end compartments matches up with the corresponding grill efi'ect produced by the fins and topand bottom walls of the radiator unit so that the whole front of the unit is given a harmonious appearance.

In new buildings, the radiator unit may be installed as shown in Figs. 1 and 5 where the same is shown installed below the window 45 between portion 46 of the baseboard and the base moulding 47 is fitted in place over the top of the unit, though such an arrangement is of course optional and in old buildings, the radiator may be set in front of the baseboard.

The radiator constructed as above described, provides the large front face 8 for the dissipation of radiant heat into the room as well as an efiicient arrangement for heatplate 39 is swung forwardly the attendant.

ing the air passing through the channels 13 and 14 by convection.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claims.

-What I claim as my invention is i 1. In a baseboard radiator, a heating unit comprising a heating chamber of substantially the length of said unit and having an exposed front wall .of similar length and forming a heat radiating surface of an area provided by substantially the length and height of said chamber, the rear portion of said chamber being formed to provide spaced channels, and fins extending from the bottom, rear and top portions of said chamber and cooperating with said channels to provide a series of spaced passages through which air passes and is circulated by convection heat.

2. In a baseboard radiator, the combination of a heating unit having a heating chamber provided with a front heat radiating surface and fins projecting from said chamber to space the same from the bottom. rear. and top of the unit and forming grill-like openings at the front of the unit, and a compartment secured to one end of said unit for concealing pipe connections for said unit and provided with front Wall portions having grill-like openings similar to those of said unit, one of said wall portions being movable to provide access to said compartment. In testimony whereof, I afiix my signature.
